Epidermal Growth Factor Receptor (EGFR) kinases control cell responses using conserved structures. This review details receptor control mechanisms, cancer deregulation, and differences between human receptors, focusing on HER2 and HER3.

Area of Science:

  • Molecular Biology
  • Cell Signaling
  • Biochemistry

Background:

  • Epidermal Growth Factor Receptor (EGFR)-type receptor tyrosine kinases mediate diverse cellular functions through conserved structural elements.
  • Understanding receptor control mechanisms is crucial for comprehending cellular signaling and its dysregulation in diseases like cancer.

Purpose of the Study:

  • To provide an overview of current models for controlling EGFR-type receptor tyrosine kinase activity.
  • To highlight new insights into receptor regulation, cancer-associated deregulation, and inter-receptor differences.
  • To specifically emphasize the roles and control of Human Epidermal Growth Factor Receptor 2 (HER2) and Human Epidermal Growth Factor Receptor 3 (HER3).

Main Methods:

  • Review of existing crystal structures of EGFR-type receptors.
